What did the surveyors from both nepal and china agree on to come of with about mt.everest said mr. dhakal
Answers
Answer:
The world's highest mountain Mount Everest is 0.86m higher than had been previously officially calculated, Nepal and China have jointly announced.
Until now the countries differed over whether to add the snow cap on top. The new height is 8,848.86m (29,032 ft).
China's previous official measurement of 8,844.43m had put the mountain nearly four metres lower than Nepal's.
Everest stands on the border between China and Nepal and mountaineers climb it from both sides.
Officials at Nepal's foreign ministry and department of survey said surveyors from both countries had co-ordinated to agree on the new height.
The agreement to jointly announce the new measurement of the Earth's highest point was made during Chinese President Xi Jinping's visit to the Nepalese capital, Kathmandu last year.Chinese authorities had said previously Mount Everest should be measured to its rock height, while Nepalese authorities argued the snow on top of the summit should be included.The Chinese surveyors had calculated their figure after they measured the mountain in 2005.
Nepal's government officials told the BBC in 2012 that they were under pressure from China to accept the Chinese height and therefore they had decided to go for a fresh measurement to "set the record straight once and for all".
The 8,848m height Nepal had been using for Mount Everest was determined by the Survey of India in 1954, but for the first time the country has now conducted its own measurement of the summit.
Four Nepalese land surveyors spent two years training for the mission, before heading to the summit.kBefore this, we had never done the measurement ourselves," Damodar Dhakal, spokesman at Nepal's department of survey, told the BBC.
"Now that we have a young, technical team [who could also go to the Everest summit], we could do it on our own," Mr Dhakal said.
Nepalese surveyors used GPS to make their calculations.
"We processed this data using internationally accepted methodology to determine the height of Mount Everest," Mr Dhakal told the BBC.
